Beijing (CNN)The last known female Yangtze giant softshell turtle has died in China, according to Chinese state media, potentially dooming the species to extinction.

The female turtle, believed to be more than 90 years old, died on Saturday more than 24 hours after local staff, together with international experts, attempted to artificially inseminate her, local newspaper the Suzhou Daily reported.

The paper said there were no complications from the attempted artificial insemination, but that a research team comprised of domestic and international experts would conduct an autopsy to determine the cause of death.

The Suzhou Daily said the experts collected ovarian tissue samples and would store them "for future use."
